BI1 BaF2 IR Windows for Liquid Sample Testing, Custom Sizes
Price range: $58.00 through $212.00
BaF2 IR Windows for Liquid Sample Testing – Custom Sizes
Product Overview
BaF2 (Barium Fluoride) IR windows are widely used for infrared spectroscopy, liquid sample testing,
and a variety of optical applications. BaF2 crystal offers a broad transmission range and excellent
optical performance, making it an ideal material for optical windows, prisms, and lenses.
This material features low stress birefringence, high refractive index uniformity, stable mechanical
properties, non-deliquescent behavior, and strong resistance to radiation damage. It is suitable for
mid-infrared optical systems and laboratory testing applications.
Available orientations include <100>, <110>, and <111>. Custom dimensions are supported
according to customer requirements.
